Hello,

I am trying to design Matlab App Designer. I want my user to input an excel file and arrays. Is that possible? If yes, please help how to do it or share a reference that would help me.

Thanks

Yes it is possible, but your question is fairly open ended. What specifically do you want to do? Do you want to push a button and insert an Excel file? I'm also not sure what you mean by input arrays unless you mean using Excel to input an array.

I have attached the required file. I made this app to answer someone's else question. For your application, I would pay attention to the readtable function to import your data.
Your data didn't meet the if condition that are found in the "Generate Plot" pushbutton's callback function. You can edit this callback in App Designer by right clicking the "Generate Plot" button while in the Design View and select Go to GeneratePlotButtonPushed callback.
Yes, readtable accepts .csv files

Let me know if you have additional questions.
